Sources: MLB has recently made several new proposals to the players association with an emphasis on sign stealing. Here they are: (thread) MLB proposed prohibiting batters from reviewing scouting cards or information during an at-bat. (Ex. A hitter could not review a scouting card placed in his helmet during an at-bat) MLB proposed that, beginning with the first pitch of the game, Club Personnel may not print any Scouting Information for the purposes of providing it to On-Field Club Personnel during the game. (Ex. No Club employees can print and deliver information mid-game to the dugout) MLB proposed permitting Pitchers/Catchers to use the wireless PitchCom device on a completely voluntary basis. (Clubs and Players have access to these devices now, during Spring Training, for testing during bullpens/games). Again, these are just proposals. It’s unclear right now how the PA will respond, but there’s an added focus on sign stealing.
The PitchCom stuff seems to make the most sense. The other ones want to take thinking out of the game in favor of offense? That's just a bad solution. The NFL changes the rules to increase offense, but not by forcing the defense to be dumber.
